US history: why did the People's party failed?

Question

And why did their attempt at forming a coalition of white and black farmers and industrial workers ultimately unsuccessful?

Answer 1

By 1896, the Democratic Party took up many of the Populist Party's causes at the national level, and the party began to fade from national prominence. In that year's presidential election, the Populists nominated Democratic candidate William Jennings Bryan; he backed the Populist opposition to the gold standard in his famous "Cross of Gold" speech. The Populists could not bring themselves to also nominate Bryan's wealthy running mate, Arthur Sewall, and nominated Thomas E. Watson for vice president instead. Bryan lost to William McKinley by a margin of 600,000 votes. The effects of fusion with the Democrats were disastrous to the Party in the South. Collaboration with the racist Democratic establishment effectively ended the Populist/Republican alliance which had governed North Carolina with the support of African Americans. By 1898, the Populists were attempting to out-flank the Democrats with a virulently racist campaign.
In 1900, while many Populist voters supported Bryan again, the weakened party nominated a ticket of Wharton Barker and Ignatius Donnelly. Thomas E. Watson was the Populist nominee for president in 1904 and in 1908, after which the party effectively ceased to exist.
